Abstract

A natural gas pipeline truncation opening grinding device disclosed by the present invention comprises a case, and a main chamber with an opening facing upward is provided in the case, a power device for driving the pipeline to rotate is provided in the main chamber, and a power device is provided in the main chamber. There is a left-right symmetrical driving device located on the left side of the power device, and two left-right symmetrical clamps powered by the driving device are arranged in the driving device, and the left and right sides of the main chamber are respectively fixedly connected There is a lifting table, and a grinding device is installed between the two lifting tables. The invented inner pipe clamp uses compressed air as the driving force. After the pipe is placed at the designated station, the pipe can be clamped and fixed automatically. Adjusting the pressure relief valve can adjust the clamping force of the inner pipe clamp on the inner wall of the pipe, so that the inner pipe clamp can clamp pipes of different diameters and lengths, and the invention can realize mechanized grinding, with high grinding efficiency and high grinding efficiency. The quality is relatively stable and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of grinding a truncated opening of a natural gas pipeline, in particular to a grinding device for a truncated opening of a natural gas pipeline. Background technique [0002] The transportation of natural gas requires natural gas pipelines. During the transportation process, natural gas pipelines need to be extremely tight to prevent natural gas leakage. Therefore, when connecting natural gas pipelines, flat cuts are required to ensure that natural gas will not leak. However, the general cutting method is hacksaw or mechanical After cutting, there will be impurities such as heavy skin, burrs, bumps, shrinkage, slag, oxides, iron filings and other impurities in the cut of the pipeline, which will affect the connection between the pipelines. Therefore, the cut of the natural gas pipeline needs to be polished. The natural gas pipeline incision grinder is mainly hand-held, and the workers need to hold the grinde...
